Kunststoffe international, Sustainable Growth
... partially bio-based reinforcing fibers has become an ‧established option in automotive construction. For example, a PU foam composite based on Covestro’s Baypreg-F-NF technology is used in the door panel on the “LQ” electric concept vehicle from Toyota Motor, Toyota, Japan, which is reinforced using fibers from the Hibiscus plant Kenaf (Fig. 5). The composite material was developed in collaboration with automotive component manufacturer Toyota Boshoku Corporation, which has extensive expertise ...

...nd 2 [2]), a combination of natural fibres and polyurethane offered the best promise. Starting materials include fibre mats, e. g. of flax and sisal, or a mixture of flax, sisal and hemp with a weight of 600 to 1200 g/m2. The special PUR system is Baypreg F from Bayer AG. The ratio of natural fibres to polyurethane varies from 65:35 to 45:55, depending on the application, resulting in final products with different basis weights (Table 1). After series of tests, the mat chosen for the A2 door tri...

... sector, the most exciting growth opportunities are currently promised by polyurethane composites. Bayer MaterialScience sees enormous growth opportunities for the so-called Baypreg materials, which enjoyed increasing market acceptance in 2003. In the area of polyurethane composite spray moulding (CSM), Bayer’s polyurethane technology partner, Hennecke, has a wealth of experience on the processing and machinery side. The technology is, however, also available from Cannon and Krauss-Maffei. Poly...

...ra-light trim components with optimum overall properties - for door side trim, rear window shelves and trunk lids. In this field, it is Bayer and its technology partner Hennecke who are continuing to be the key players with the NafpurTec technology (Baypreg F, natural fibres as reinforcing material), although other suppliers like BASF and Cannon are also very active in this segment. Sandwich composite materials with glass fibre matting as the facing layer and honeycomb-structured paper inside, f...

...ter recovery, can be fulfilled by this adjustment possibility. Some sports fans undulate over waves instead of over a bumpy course – with their surfboards. Their covering frequently consists of fibre-polyurethane composite materials (Baypreg). They are very light, hardly swell in water and with their high impact strength also withstand hard blows. And for long rides comfortable saddles with cushioning made of Technogel pay for themselves. Behind this polyurethane material there is a gel compose...
Kunststoffe international, 2005-11-21, PUR Composite Spray Moulding (PUR-CSM): Open to Many Different Applications
PUR Processing Open to Many Different Applications PUR Composite Spray Moulding (PUR-CSM). A new system variant of polyurethane spray technology involves the use of an isocyanate plus a fast- and a slow-reacting polyol. Depending on requirements, various additives, such as colour components, blowing agents or chopped reinforcing fibres, can be incorporated. For the production of moulded parts, only one mould half is required and no mould carrier. Ingo Kleba Thomas Kirsten In processing a rea...

...the field of small to medium-sized production runs as a result of cost-effective production are particularly impressive here. In the field of PUR composites, Bayer MaterialScience offers big opportunities for the Baypreg spray system. A more lightweight honeycomb core is covered with high-tensile cover layers and impregnated with the spray system and subsequently pressed at slightly elevated temperature to produce the finished sandwich composite system. It is superior to other, generally heavie...

...ray-moulded layers. (CSM technology naturally also covers processing by the classical PU chopped glass fibre method in which moulding takes place in a closed mould.) Alongside this application, the same system can also be used to spray PU onto Baypreg semi-finished sandwich products, comprising glass fibre mats and a paper honeycomb core, and then compression mould them into highly robust sandwich components. Baypreg technology thus currently constitutes the standard when it comes to lightweight...
Kunststoffe international, 2007-09-19, Versatile Material with Unlimited Potential?
Versatile Material with Unlimited Potential? Polyurethanes (Trade-fair-pre-report K 2007) The global market for polyurethanes has been growing steadily for years. It is driven by the desire for comfort, as in the furniture and automotive sectors, and for robust or tactile surfaces. At the K 2007 international plastics exhibition, manufacturers and processors will be providing information on new developments in these sectors. Virtually no other material combines an attractive appearance wit...

...PU sandwich construction. The “PU sandwich”consists of a honeycomb cardboard core sandwiched between two glass fiber-reinforced skins that are pressed together in a mold using a sprayed two-component PU system such as Baypreg F. In the meantime, Bayer MaterialScience has refined the process to the point where lightweight load floors in automobiles can be produced with a colored, grained softtouch surface in a single process step (Fig. 4). They have also succeeded in extending the process...

...llel with that, a PU sandwich package comprising a cardboard honeycomb core laminated with glass fiber mats on both sides, is produced in a separate spray cabin as carrier layer. The sandwich is sprayed on both sides with the 2-component PU system Baypreg F and then laid on the already cured Baytec layer in the press mold. The entire structure is then heat pressed at about 130°C, during which the slightly foaming Baypreg F firmly bonds the individual composite components together. This results i...
